Remember Cuppow? It's that genius attachment that turns any jar into a travel carafe. Now its creators have returned with the BNTO, an insert that for $7 turns your mason jars into lunch boxes.

BNTO basically looks like a plastic jello container. You just stick it in the top of your jar and screw the lid on and it separates your ingredients. Want to keep your salad away from the dressing until lunch? BNTO. Want your chips sequestered from your dip? BNTO. The 6-ounce, $7 attachment is a pretty savvy solution for using the things you already have laying around your house and would probably throw away otherwise. Besides, nobody likes a soggy snack.
